91-acre Bahía de Sardinas fishing map with NOAA BlueTopo survey contours (100% measured, 100% assessed), source-traceable coastal structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 55 ft. The depth chart is built from real agency bathymetry referenced to NAVD88; directly measured coverage remains distinguished from source interpolation. The channels, holes and drop-offs come from the source data, not a distance-from-shore model. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 91 acres of water rimmed by 1.7 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 55% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.5 mi end to end and 0.4 mi across at its widest. The nearest mapped water is Bahía Tamarindo, 2 mi to the northwest.
When the water first warms, atlantic tarpon slide up into 3 to 25 ft. By summer they slide out to 4 to 35 ft, and by winter most fish are in 5 to 35 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 17 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a heavy paddletail or a swimbait in pass current rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Surveyed channel edge (17 ft) | 4-6 inch paddletail, Suspending baitfish plug |
| Summer | 4 to 35 ft | dawn & dusk | Surveyed channel edge (17 ft) | Heavy paddletail, Swimbait in pass current |
| Fall | 3 to 30 ft | dawn & dusk | Surveyed channel edge (17 ft) | Mullet-profile swimbait, Surface plug |
| Winter | 5 to 35 ft | dusk | Surveyed channel edge (17 ft) | Slow-rolled paddletail, Suspending plug |
Start shallow in spring: jack crevalle sit in 2 to 25 ft that time of year. Warm water sends them out to 3 to 35 ft; cold water stacks them in 5 to 35 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 17 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a pencil popper or a casting spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 25 ft | dawn & dusk | Surveyed channel edge (17 ft) | Surface popper, Metal jig |
| Summer | 3 to 35 ft | dawn & dusk | Surveyed channel edge (17 ft) | Pencil popper, Casting spoon |
| Fall | 2 to 30 ft | dawn & midday | Surveyed channel edge (17 ft) | Topwater walker, Metal jig |
| Winter | 5 to 35 ft | dusk | Surveyed channel edge (17 ft) | Compact metal jig, Slow-rolled paddletail |
Start shallow in spring: yellowtail snapper sit in 7 to 55 ft that time of year. They don't go far with the seasons — 8 to 55 ft covers summer, 8 to 55 ft covers winter. The spot to know is NOAA charted rock, a hard bottom in about 13 ft of water that rates prime for yellowtail snapper in spring. Warm-month bites cluster around early morning and the evening. Throw a micro jig or a small paddletail until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 55 ft | dawn & dusk | NOAA charted rock (13 ft) | Small bucktail, Light vertical jig |
| Summer | 8 to 55 ft | dawn & dusk | NOAA charted rock (13 ft) | Micro jig, Small paddletail |
| Fall | 8 to 55 ft | dawn & dusk | NOAA charted rock (13 ft) | Small vertical jig, Baitfish streamer |
| Winter | 8 to 55 ft | dusk | NOAA charted rock (13 ft) | Small jig worked deep, Bucktail |
Early season mutton snapper use the shallows, holding in 7 to 55 ft. Even in summer they hold at 7 to 55 ft; winter keeps them in 9 to 55 ft. Put NOAA charted rock first on the milk run — a hard bottom near 13 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a heavy bucktail or a vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 55 ft | dawn & dusk | NOAA charted rock (13 ft) | Bucktail near bottom, Paddletail |
| Summer | 7 to 55 ft | dawn & dusk | NOAA charted rock (13 ft) | Heavy bucktail, Vertical jig |
| Fall | 7 to 55 ft | dawn & dusk | NOAA charted rock (13 ft) | Bucktail + strip, Slow vertical jig |
| Winter | 9 to 55 ft | dusk | NOAA charted rock (13 ft) | Slow jig, Bottom bucktail |
Early season great barracuda use the shallows, holding in 2 to 45 ft. Summer is a 3 to 55 ft game here, winter a 4 to 55 ft one. The chart's best answer is NOAA charted rock bottom — hard bottom, 4 ft, prime for winter. Best bite is early morning and the evening. Tie on a fast swimbait or a spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 45 ft | dawn & midday | NOAA charted rock bottom (3 ft) | Fast tube lure, Long minnow plug |
| Summer | 3 to 55 ft | dawn & dusk | NOAA charted rock bottom (3 ft) | Fast swimbait, Spoon |
| Fall | 3 to 55 ft | dawn & midday | NOAA charted rock bottom (3 ft) | Mullet-profile plug, Tube lure |
| Winter | 4 to 55 ft | midday & dusk | NOAA charted rock bottom (4 ft) | Long minnow plug, Fast jig |
Spring gray snapper (mangrove snapper) on Bahía de Sardinas hold shallow, usually 3 to 22 ft. By summer they slide out to 4 to 30 ft, and by winter most fish are in 8 to 45 ft. The chart's best answer is NOAA charted pier — dock line, 2 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small bucktail or a paddletail.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 22 ft | dawn & dusk | NOAA charted pier (2 ft) | Small paddletail, Jighead + shrimp imitation |
| Summer | 4 to 30 ft | dawn & dusk | NOAA charted pier (2 ft) | Small bucktail, Paddletail |
